To prevent individual users from consuming excessive session table resources to cause connection failures of other users, enable the NAT64 session number limit function.
If the number of established Transmission Control Protocol (TCP), User Datagram Protocol (UDP), Internet Control Message Protocol (ICMP) NAT64 sessions, or the total number of NAT64 sessions of a user exceeds a configured threshold, a device stops establishing such sessions. The limit helps prevent resource overconsumption from resulting in a failure to establish connections for other users.
